how to change valve cover gaskets on a Porsche Cayenne 955 V8 

DO NOT cut the wire for the AC compressor, if you look straight down on the top of the compressor there is a connector. Disconnect the wire will give you enough slack to remove the left valve cover, you do not need to pull the wire all the way out just uncouple will give you enough room. The video is good just wanted to point this out, you already had the wire cut and my valve covers were missing bolts, wonder why it leaked? That's what happens with 2nd hand vehicles you have to live with other peoples hacks. so DON'T hack the A/C wire.

Torque spec is 7 lbs. It is easy to overtorque.

Best video Tutorial for valve cover and gaskets. You the man! Thank you very much….and yes, the little 1/4” drive is a life saver!

Incredible video. Please dont stop

Great 👍 work Down to earth 🌎 you got a dog even better.

Brother you save my ass with that little tool ratchet

Lessons learned while doing this a few days ago: 1. Be careful removing the passenger side air box - there is a nipple for an air hose on left side that I broke, tried epoxy, but didn't work, ended up with duct tape. 2. Be careful when moving hoses around near the firewall on passenger side - I broke the plastic 'Y' that is part of the manifold vent hose, it's around $100 to replace (goes to manifold, intake plenum, and somewhere else)...I used heat resistant stretch tape as a temporary fix. Same goes when removing and replacing the air pump bracket because it puts pressure on that fitting. 3. The A/C wire that runs across the driver's side valve cover has very little slack and it is a pain to slide the cover in and out, and you will risk either smearing your new sealant if you use some, or damaging the camshaft fingers ($$$$$), just cut and reconnect as he did in the video. 4. Make sure not to over torque your plugs and ruin the threads in your heads ($$$$$). I believe the the spec is 22 Nm (30 ft-lbs), but don't quote me. I stopped at 15 ft-lbs just to be safe. Figured I could always go back and re-tighten if I'm losing compression - better safe than sorry. 5. Finally, those valve cover bolts in the back corner near the firewall are a bitch...get ready for a fight, and good luck!

Hello! Can I start engine with on missing bolt on the upper side of cover gasket? Thanks

Thanks for the help! Done mine today was a right pig to do , but done it!!

Im see this video 2 times and I’m fix my Porsche on 2 ours, more easy the back bolts with 1/1/4 and the bolt T140 I’m put little bag plastic like this no lose the bolt

This very good video and my shade-tree skills will save me $$$. An independent garage quoted $700 for doing the gaskets on my 2006 Cayenne S. I'm much more confident at tackling it after seeing it. Thx bro!

Getting mine done on the 22nd of march to put new plugs in and the valve cover gasket it's almost 800 dollars

Hi, great video. I need to change bank 1 camshaft actuator, hence valve cover removal. I've read horror stories about damaging something called the "cam fingers"...you know anything about that? Also, which side is bank 1? 04 Cayenne Turbo. Thanks.

Great vid - helped a lot for my gasket replacements... worst part for me is the vacuum-hose on the passenger cold-air box - can't get it off!

Thank you 🙏🏼 Was very helpful!

there is a very small step in the covers near the front that needs a dab of gasket sealant when you replace them. When i took mine off, I could see the old dab of a red sealant that was used previously.

Very helpful just got done with mine thank you!

Did you install the seal for the timing adjustment solenoid before putting the cover on or should it be installed when the cover is torqued down? Thanks for sharing, got the mini wrench and getting ready to start

Very helpful thanks!!!

Good job! Thanks for this video!

Nice no nonsense video, thanks man

Very nice video thanks for sharing! 👏

Do you think the round gasket by the valve sensor x2, these are the electrical connections on the front of the valve cover, can be swapped without taking the valve cover off? I smoke tested the oil filer cap and smoke rolled out of the sensor seals.

Hello, Do you work more on Porsche cars?

You’re the other other Cayenne owner to use K&N panels filters. My S has just started a weep from bank 1 valve cover gasket.

Thank you for the video.

This guy doesn’t show removing the three back valve cover bolts which are a complete pain to get to. Around 6:05 , he completely skips over those. I found the top and bottom ones but I missed the middle back one because I didn’t know it was there and cracked my valve cover on my driver side. Very thorough. Thanks. 🤬

Bro 😎 thank for all the help because I will be damn 🦫 if I will take my wife Porsche to the dealership $1500 where I’m gonna send you a video when I’m done ✅ 🔥🚙🚘🚘 thank bro 😎 p,s I did the Engine oil transmission oil back in front resuspension

I have a 2006 Cayenne S with 157K and thinking this is my problem now. Very faint smoke from driver side and the burning smell occasionally. I will probably pay the $600 for this to prevent me breaking my cam sensor costing me even more after watching this.

great job , great video. why didn't you just install a quick disconnect on the wire you cut. And why not JB weld your cover?

why was the reasion to change the valve cover gasket was if because it was making ticking lifter noise also can i clean the lifter by removing this cover only

Do you still own the 1st Gen Cayenne? I've been finding your videos very informative.

PLZ help! I've replaced the valve cover gaskets, intake gaskets, spark plugs and water pump on my 955 V8 but now its running very rough (rough idle) and the engine smells likes it's burning. I did what I could to bleed the cooling system, I don't have any fancy equipment so I did the let car idle with the heat on its highest setting with the expansion tank cap off, the vehicle really didn't seem to heat up although I was only able to run the car for 1-2min before shutting it off due to rough idle and smell of burning motor . I've tripled checked all my wiring/fuses and measured voltage/resistance to coils and fuel injectors and everything turned out to be fine, all 8 cylinders are running. The only think I can of now, and didn't check is the valve cover gaskets not being properly seated, I did noticed the gasket for the spark plugs/coils seemed as if it was able to get positioned multiple ways, how did you go about placing that gasket?

This was super helpful. Which Torx bit does that back bolt need?

Huge timing chains

my engine inknocking and psi is onli 90psi compression on cylender 8 and the knocking comes from there my pvc valve as clugged dirty any help

Nice job!

Thanks alot. Keep it up

Out of curiosity, at what mileage did the gaskets go out? I am waiting on Carvana to buy a 2010 Cayenne S with 57K miles on it. I want to put a tow hitch on it to pull a camper (under the 7700 lbs limit)

Hello, I have a cayenne turbo 4.5, it starts very cold, it starts very hot if it is not stopped for more than 10 or 15 minutes, if there is more time stopped it takes 10 seconds to start and it does so as if it were drowned with fuel, and replace the crankshaft position sensors and camshafts, repair the pcv valve, check the canister, bovines, spark plugs, maf, everything is ok, there are no errors when scanning, something curious if I inject air through the canister hose to the intake manifold, it turns on well, the truth is that I have fried, something similar happened to you? Thank you very much in advance, greetings from Argentina

Dude, this is the best video on taking down to the valve covers. Great job!! You can probably do well refurbishing these engines. Makes me want to give up the pen for a machine project like this. The vehicle is undeniably great, as shown by the mechanics. Just wish there were more thought in the year down process. E.g., why bury the starter underneath the coolant pipes made out of cheap plastic.

Hey this is an excellent video. I wish I had seen it before completing my car. What is the tool you use at 3:44 to remove the air pump bracket? Also when i torque to porsche specs they break, so i just hand tightened.

This the best
